UK Buy to let Landlords to lose Income Tax Relief

The 2016 UK Budget – Buy to let Mortgages..

Income tax relief enjoyed by landlords will be cut to the basic rate of just 20% with a gradual phase in from 2017.

The Daily Telegraph states this:

Currently interest payments of £100 only cost £55 after tax relief, but will cost £80 from 2020.
A landlord who borrows at even a modest level might end up paying more in tax than he makes in profit.
